Home theaters are similar to cars!
How fast you want to go depends on how much money you're willing to spend. Same with home theater, I'm sure some members could point you in the right directions but they'll need to know your budget. Of course the more involved you become the higher your budget seems to go.
As far as installers etc. use google and check out the Display Calibration threads on the AVS forum.
